The R1155 receiver dates back
to WWII, and was famously used in the Lancaster Bomber, but could also be found
on land and at sea. It comes in many variants, indicated by a letter suffix
(e.g. R1155A, R1155B, etc).

We have been offering the R1155 full manual for free download
for some years - here it is again, but this time in the more friendly Acrobat
format.
